Comu Action Pro - An AI Meeting Recorder Just 7mm Thick That Sticks to the Back of Your Phone

Meeting recorders usually end up sitting alone in the middle of a desk. At 7mm thick, the Comu Action Pro looks more like something that travels alongside your phone, stuck to its side or back. I think it will catch the eye of anyone who wants to stay focused in meetings and hand off the note-taking.

✨ 3-Line Summary
- 👍 Biggest strength: It's thin enough to stick on the back of your phone, so it barely feels like one more thing to carry.

- 🎯 Recommended for: People with frequent meetings who want a dedicated recorder instead of their phone's call app
📸 Product Tour

Even held in your hand while attached to the back of a phone, it adds almost no bulk. The small screen shows the recording time.

This shows it being used for calls or recording while stuck to the back of the phone.

You can also lay it flat next to your laptop.
🔍 Why It Caught My Interest
It can travel alongside your phone
A dedicated recorder is great, but carrying one more device was a hassle. If it's thin enough to stick on the back of a phone, that burden should shrink a lot.
The screen and buttons are minimal
The small screen shows the recording time and a waveform, and there are just two buttons: AI and record. I like how stripped-down it is.
It mentions several AI models
The images show names like ChatGPT, Claude, and Gemini. How it integrates with them still needs to be confirmed.
🤔 What Gives Me Pause
Privacy and subscription
I couldn't confirm where meeting recordings get sent or whether the summaries require a paid subscription. If you plan to use it for work meetings, you'll definitely want to check.
Your phone's app might be enough
Phones now have built-in recording and summarizing features, so a dedicated device needs a clear advantage.
📋 Product Traits (Subjective Ratings)

🛒 Pre-Purchase Checklist
✅ Recommended for
- People with lots of meetings or lectures who want to automate note-taking
- People who prefer thin, lightweight devices
❌ Not recommended for
- People uncomfortable sending voice data off-device
🎯 Final Verdict
The Comu Action Pro is built around a single idea: it's so thin you'll always carry it. The quality of its AI summaries still needs confirming, but the form factor alone makes it interesting.
Once the price, pricing plan, and data handling are confirmed, it's worth putting on the shortlist.
